N O T E : A ll axle attachments are im portant attach­
ing parts in th at they could affe ct the performance
o f vital components and systems, and/or could
result in major repair expense. They must be re­
placed w ith parts o f the same part numbers or w ith
equivalent parts if replacement becomes necessary.
Do not use replacement parts o f lesser quality or
substitute design. Torque values must be used as
specified during reassembly to assure proper reten­
tion o f these parts.
Removal
1. Raise vehicle on hoist, and rem ove rear wheels.
2. Rem ove tw o tru n n io n bearings “ U ” b olts from the rear
y o k e ; split rear universal jo in t; positio n propeller shaft to
one side, and tie it to th e fram e side rail.
N O T E : The bearings can be left on the trunnion
and held in place w ith tape.
3. Rem ove brake drum and disconnect parking brake cable
at lever and at flange plate. (See S ection 5 for cable
rem oval.)
4. D isconnect hydraulic brake hose at connector on rear
axle housing. ( I f vehicle is equipped w ith air brakes,
disconnect air line at brake cham bers, and tie lines o u t o f
th e w ay.)
5. D isconnect shock absorbers at axle brackets.

. S u p p o rt axle assembly w ith hydraulic ja ck , remove spring
“ U ” bolts, and low er axle assem bly to the floor.
Installation
1. Place axle assem bly u n d er vehicle, raise into position,
install spring “ U ” bolts, anchor plates and nuts, and
tighten securely.
2. C onnect and secure shock absorbers to axle brackets.
3. C onnect hydraulic brake hose to connector on axle
housing, and bleed hydraulic system as specified in
Section 5.
4. C onnect hand brake cables and adjust parking brakes as
specified in S ection 5.
5. Reassem ble the rear universal jo in t, m aking sure th a t “ U ”
bolts are draw n up tight and locked properly. T orque to
specifications.
6
. Install rear wheels, remove stand jacks, and low er vehicle.
7. T est operation o f brakes and rear axle.
Axle Vent
Replacement
Service replacem ent axle housing assemblies are n o t equ ip ­
ped w ith an axle vent; therefore, always m ake sure th a t a new
vent assembly is installed w hen replacing th e housing. If axle
vent requires replacem ent, pry old vent form housing being
sure th a t entire vent is rem oved. Prick p unch around carrier
hole to insure fit o f replacem ent vent. Tap new vent into
housing using a soft-faced ham m er. V ent should be positioned
in housing so th a t flat surface is tow ard centerline o f differ­
ential carrier (fig. 18).
Axle Shaft
Removal and Installation
1. Rem ove b olts and lock washers th a t a tta c h th e axle shaft
flange to th e w heel hub.
2. Install tw o 1/2"-13 b olts in the threaded holes provided
in the axle shaft flange. By turning these bolts alternately
th e axle shaft m ay be easily started and then rem oved
from the housing (fig. 19).
3. T horoughly clean b o th the axle shaft flange and the end
o f th e w heel hub.
N O T E : A n y lubricant on these surfaces tends to
loosen axle shaft flange bolts.
4. Place a new gasket over th e axle shaft and position the
axle shaft in the housing so th a t the shaft splines enter
the differential side gear. P osition gasket so th a t holes are
in alignm ent and install flange-to-hub attaching b o lts—
torque bolts to specifications.
N O T E : To prevent lubricant fro m leaking through
flange holes, apply a non-hardening sealer (such as
Permatex Type A or equivalent) to b olt threads. Use
care in the am ount o f sealer applied, as in too heavy
an application, the sealer may be forced out as the
bolt is installed and may destroy sealing effect o f
the flange-to-hub gasket.
